Airborne Topo-Bathymetric Lidar Combined with Thermal Imaging for Fish Habitat Studies in RiversResearchers at Nova Scotia Community College’s Applied Geomatics Research Group have been using the airborne Leica Chiroptera 4X topo-bathymetric lidar sensor for nearly a decade and have surveyed coastal, riverine and lake environments. They have concentrated on mapping submerged aquatic vegetation (SAV). Topo-bathy lidar data of rivers provides an opportunity for improved flood hazard h...
As traditional infrastructure design methods migrate from 2D to 3D modeling, LiDAR data acquisition continues to present an opportunity to improve the base modeling process. This presentation will show how TopoDOT can be used to extract DGN vector data from point clouds to improve the quality of digital as-built base models which enable better transportation 3D design processes like Bentley’s ORD.
Canada has just experienced a record wildfire season with devastating impacts. Public safety and damage mitigation is a priority for all impacted by these disasters. From mapping vegetation, analyzing slope stability, planning fire breaks, qualitfiying wood debris and fuel loads, how does LiDAR play a role in meeting post wildfire needs?

The new Canadian Hydrospatial Network (CHN) is set to replace the National Hydrographic Network (NHN) for Canada. Designed for improved use in hydrological models, the CHN is analysis ready with full-network traversing ability, and value-added attributes such as stream order. The CHN is also created from higher-resolution source data and better aligned to elevation than the NHN, where possible, and has been streamlined for production and maintenance.Work is on-going to refine methods a...
Subsea acoustic sensors, including multibeam sonars and sub bottom profilers, provide users with a variety of data types to improve our understanding of the marine environment and effectively manage important resources. This includes bathymetry, which is a foundational layer for analysis, but also information on the bottom reflectivity to characterize sediment types, water column data to map mid-water material and organisims by providing a view from the sensor to the floor of our rivers and l...
The Alberta Biodiversity Monitoring Institute (ABMI) defines human footprint as the visible alteration or conversion of native ecosystems to temporary or permanent residential, recreational, agricultural, or industrial landscapes. It also includes land that is periodically reset to earlier successional conditions by industrial activities such as forestry harvest areas and seismic lines. To monitor and map human footprint across Alberta, the ABMI, in partnership with the Alberta Human Footprin...
From ancient cave drawings depicting hunting grounds to hand-sketched layouts of backyard gardens, humans conceptualize space through map making. Maps serve both to capture what exists on the landscape and to plan future uses by intentionally defining where specific activities can happen. Modern satellite technology creates geospatial datasets that can contribute to current and proposed land use management planning, all underpinned by the pursuit of the public good.Background
The session will focus on considerations for deploying Artificial Intelligence in professional practice; identifying potential landmines and working on solutions from a privacy-first perspective. The talk will include a high-level overview that underscores the fundamental components that encapsulate an AI derived “solution” and delve into a practical, real-world example being tested on an active project.Topics Covered:• An illustrated example of BIM model query using AI• AI too...
Too often, when discussing the value proposition of geospatial data, we focus in on raw data or output products without spending a lot of time in the juicy middle of data throughputs. That is to say that modern geospatial is leaving a lot of value on the table and thus limiting our ability to good with our data by: -> Focusing too heavily on the capturing aspect of geospatial technologies;-> Ignoring or discounting analytical capabilities of geospatial technologie...
In 2021, the Government of Canada invested $63.8M in the Flood Hazard Identification and Mapping Program (FHIMP) to to create and disseminate engineering-level flood hazard maps that can help Canadians better plan and prepare for future flood risks. The program was recently extended to 2028 through the National Adaptation Strategy and enhanced with an additional $164 Million investment.Given that many Canadians are unaware of flood hazards, the FHIMP is working to fill gaps in knowledg...

The government of Alberta manages the production of riverine flood studies under the provincial Flood Hazard Identification Program, to assist communities in keeping Albertans safe and protecting their properties from floods. Flood maps improve public safety, support emergency management, and help us build safer and more resilient communities. The government of Alberta also manages the production of alluvial fan studies to help Albertans learn about flood risks in the steep terrain of Alberta...
The health of the global ocean environment is of critical importance. Planetary limits for climate change and biodiversity are being reached, and unsustainable resource management practices are rampant. Space-based Maritime Monitoring has proven to provide foundational support for sustainable management of ocean resources. In the Keynote, John will provide a high-level overview of ocean problems, space-based maritime monitoring, the beneficiaries and outcomes of the application of...
The integration of AI in infrastructure modeling has the potential to revolutionize decision-making processes by providing accurate predictions, identifying vulnerabilities, and optimizing resource utilization.The increasing complexity of modern infrastructure systems, coupled with growing demands on utilities, has necessitated the adoption of advanced analytical techniques. This panel discussion brings together ideas from acad...
Methane is a greenhouse gas that has a global warming potential 80 times greater than carbon dioxide over a 20-year period. Reducing methane emissions from industrial facilities is one of the most effective ways to reduce greenhouse gas emissions. This talk gives an overview of GHGSat’s approach to providing stakeholders actionable data by detecting, geolocating, and quantifying methane emissions using our fleet of space-based and airborne instruments.

Case Study: How DOTs and Utility owners took a Proactive Approach to Protect Underground Pipeline Assets Due to aging infrastructure and lack of accurate utility location information resulting in huge increased operational risk & especially at waterway, transportation, and ROW utility crossings. Utility owners understand the significant underground congestion and utility conflicts which result in future damages and the value the importance of geo location of UNLOCA...
Local governments have been updating their asset inventories to comply with the TCA legislation since the early 2000s, paying particular attention to the attributes, locations, ages and conditions of their assets. However, infrastructure changes constantly due to capital projects and land development, especially in fast-growing municipalities like Kelowna. Collecting accurate and complete information on new assets has been a major challenge, mainly due to limited staff resources. To address t...
